Clang-3.2 compiles (FWIW), but rejected by GCC 4.7.1 and 4.8:
------------------------------------------------------------------
#include <functional>
template<class T=void>
struct c{
std::function<int(int)> f = [](int i){return i+i;};
};
int main() {}
-------------------------------------------------------------------
Error message:
